At least four adult men have come forward in the past four months to say they were abused by Collins when he was the swim instructor.

One of the men has accused Collins of forcibly raping him at the club in 1980. That accuser told investigators his father confronted Collins and the club at the time about the allegation. The club's director immediately fired Collins and told him to leave the area, but no charges were ever filed.

Collins, according to officials, spent the next 33 years moving from state to state, eventually landing in Centereach, N.Y., where he was arrested.

Authorities claim Collins has confessed to two of the assaults, but "can't remember the others."

The judge at Collins' arraignment entered a plea of not guilty on his behalf.

He faces four charges in all, one for each of the alleged victims.

Collins is the second former worker at the club to be accused in an alleged sex abuse scandal spanning from the 1970s to the 1990s. Former program director William "Sully" Sullivan, who died in 2002, is accused of sexually assaulting at least two victims from the 1970s through the 1990s.

He was never charged.

Team 5 Investigates reported in February that at least one parent had warned the Arlington Boys and Girls Club in the 1990s about Sullivan, but nothing was done.

"While there is obviously great distress and sadness about these events, the Club’s leadership today remains vigilant and committed to assuring the safety and wellbeing of all children who attend the Club," the Boys and Girls Club said in a statement.

A maid who cleaned the home of former New England Patriots player Aaron Hernandez has testified at his murder trial that she saw him "messing with" the security camera in his basement the day after the killing.
